Technical Area

This invention is about laparoscopic surgery, which is applied by other branches such as health sector, medicine, mostly general surgery, and sometimes gynecological and urological surgery.

Current state of the Technic

Since it occupies a large area in the abdomen and enters the operation area during abdominal surgery, narrowing the field of view and increasing the possibility of injury during the abdominal surgery; it is appropriate to remove the small bowel loops with the help of a retractor. Although there are many options in open surgery, these options are narrower in laparoscopic surgery. An endoscopic sponge, called an endoractor, is commercially available to retract small bowel loops during colorectal surgeries.

Endoractor, as it is known, is a long and thin rectangle, which can expand in volume when soaked. It is produced from a spongioform material that enables the retraction of the surrounding structures, and is a flexible structure that will not break down during manipulations in the abdomen. In laparoscopic surgery, after this device is placed from the trocar hole into the abdomen in the position where the small intestine loops need retraction, its volume is increased by soaking it with physiological saline through the endoscopic serum irrigation system and effective retraction is provided to perform colorectal surgery. At the end of the surgery, it is taken out of the abdomen through the same opening as the resected colonic segment, not through the trocar hole due to its enlarged volume. Due to its rectangular shape, it is useful for retraction of the small intestine during laparoscopic colorectal surgery, and publications have reported that it is used for retraction of the small intestine in various laparoscopic gynecological surgical procedures. However, due to its shape, it is not suitable for practical use for retraction of intra-abdominal solid organs.

Purpose of the Invention

The aim of this invention, which is presented as a crescent endoretractor, is to provide more effective retraction than standard endoscopic sponges in rectangular structure. After the volume is increased when wet, by curling it into a crescent shape, the volume increase in the center is greater than the periphery and the retraction force of the center region is higher. Retraction of solid organs, especially the spleen, which enters the operation area in various upper gastrointestinal system surgeries, especially in bariatric surgery, and also in surgeries such as laparoscopic surrenalectomy, the use of a crescent endoractor for safer exploration increases the surgical efficiency and can be positioned more comfortably. Providing ease of manipulation, it is also expected to reduce injury rates of solid organs compared to other blunt retractors and/or surgeries without endoscopic sponges.

2. Crescent shape of the endoretractor with an increase in volume after wetting Description of the Invention

The crescent endoretractor is placed into the abdomen through the trocar hole after appropriate exploration is done following pneumoperitoneum (1 ). Then, the endoscopic serum is wetted with the irrigation set and its volume is increased as needed. After wetting, the endoractor takes a crescent shape (2) with an increase in volume, it is placed in the desired position by taking advantage of its ability to be easily manipulated by laparoscopic hand tools thanks to the structure. After the completion of the surgery, it is taken out of the abdomen through the opening where the resection material is removed.

Industrial Application of the Invention

Crescent endoretractor; can be easily produced in all kinds of industrial establishments where standard endoractors, known as endoscopic sponges, are produced in the market and can be produced from the same materials.
